Check IIS Site Statistics.
Available counters are: TotalAnonymousUsers, TotalConnectionAttemptsAllInstances, TotalGetRequests, TotalPostRequests, TotalBytesReceived, TotalBytesSent, TotalFilesReceived, TotalFilesSent
Counters are per seconds.
=over 8
=item B<--warning-COUNTER>
Warning threshold for counters.
=item B<--critical-COUNTER>
Critical threshold for counters.
=item B<--name>
Set the site name.
=item B<--regexp>
Allows to use regexp to filter site name (with option --name).
=item B<--add-counters>
Can add the following counters (not by default): TotalBytesReceived, TotalBytesSent, TotalFilesReceived, TotalFilesSent
Counters are separated by comas.
